The timer is a clockwork device and does not require batteries, so you must watch the video operation and don't mess around. I won't ask the customer service, and I will teach you until you can.

The gap in the middle of the timer is normal on one side, which is designed for accurate time.

[Special note]]: timer products lose the timing effect due to accidental reverse operation by customers. Therefore, this product does not have any after-sales service and does not accept returns or exchanges for any reason. Please purchase with caution. If you do not follow the method described in the instructions above, reverse operation will cause the product to lose its effect.
